NIPPLE FOR EARTHENWARE CONTAINERS.

Application filed May 15, 1925. Serial No. 30,518.

To all whom t may concern.'

Be it known that I, GEORGE HENDERSON, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful mprovements in Nipples for Earthenware Containers, of which the following is a specification.

My invention relates to an improvement upon the nipple described in my Letters Patentof the United States, No. 1,043,230, of November 5, 1912. 1t has been the special object of my invention to render more secure the means for mounting and holding in position the lugs which embrace the in ner surface of the earthenware container adjacent the aperture therein in which my nipple is mounted.

h/[yrdevice may be best understood by reference to the accompanying drawings in which- Fig. 1 is a side view cross-section of my device mounted in an earthenware container, a port-ion of which container is shown broken away. p

Fig. 2 is a bottom view of my device.

Referring now more specitically to the drawings, 1 is a cylindrical sleeve which is screw threaded on its outer surface and which is provided in its lower portion with a cross-rod 2 which extends across the base of the sleeve 1 upon the diameter, being securely supported in opposite holes in the sleeve 1.

T he sleeve 1 is adapted to tit closely within an annular hole in the surface of an earthenware container 3. Slidably mounted upon rod 2 are rectangular lugs 4 and 5 which are provided with holes in the upwardly extendingl port-ion thereof so that the lugs may be moved along rod 2. To insert the sleeve and lugs within the hole in the earthenware container, it is necessary to slide lugs l and 5 between each other so that they will meet near the center of the rod 2. After being passed throiilgh the opening in the container the lugs lland 5 may then be slid into the positions shown in Fig. 1 wherein they underlie the adjacent lower surface of the container 3.'

A locking ring 6 is screwed about the outer threaded surface of' the cylindrical sleeve 1. Beneath this locking ring G is a gasket 7, and upon screwing down the locking ring G a firm contact of the gasket 7 with the top of the container is made and at the same time the lugs l and 5 are drawn into firm engagement with the end surface of the container. Considerable stress is required to effect a firm joint. Such stress has a tendency to slightly bend the rod 2 downwardly, particularly if the lugs 4 and 5 slip even slightly toward the center of the rod 2. l have found that it is very important to check such slipping as there is increasing tendency to slip, once any slipping is developed. lt is very important that the upwardly extending portions of lugs fl and 5 be always maintained in close aud even engagement with the inner surface. of the sleeve 1. Hence, l have provided a roughened surface for the rod 2 which is very elfectively done by providing the rod 2 with a screw threaded surface. Such a surface will effectively prevent any slipping of the lugs Ll and 5 and will retain the parts always in the desired position.

The top of the nipple is closed by the screw cap 7 within which is litted a disc S made of rubber cork or other conipressible material so as to secure a tight closure. It l will be readily understood the-.t all parts of my device are made of metal, except the gasket 7 and the disc 8.

Having thus fully described my invention what l claim is:

ln a device of the character specified the combination of a sleeve arranged te be in` serted in an opening in an earthenware container said sleeve being screw threaded upon its exterior, a roughened rod mounted in the lower portion of said sleeve and extending across the same, lugs slidably mounted on said rod, a threaded locking ring arranged to be screwed down upon said sleeve, and a gasket beneath said locking ring.

In witness whereof l have hereunto afiixed my signature.

GEORGE HENDERSON.
